These books go beyond the technical documentation to explore the nuances of network architecture,
deployment, and administration. The current list can be viewed at https://www.juniper.net/books.
Using the Examples in This Manual
If you want to use the examples in this manual, you can use the load merge or the load merge relative
command. These commands cause the software to merge the incoming configuration into the current
candidate configuration.The example does not become active untilyou commit the candidate configuration.
If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example
is a full example. In this case, use the load merge command.
If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In
this case,use the load merge relative command. These procedures aredescribed in the following sections.
Merging a Full Example
To merge a full example, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration example into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following configuration to a file and name the file ex-script.conf. Copy the
ex-script.conf file to the /var/tmp directory on your routing platform.
system {
scripts {
commit {
file ex-script.xsl;
}
}
}
interfaces {
fxp0 {
disable;
unit 0 {
family inet {
address 10.0.0.1/24;
}
}
}
}
xi
2. Merge the contents of the file into your routing platform configuration by issuing the load merge
configuration mode command:
[edit]
user@host# load merge /var/tmp/ex-script.conf
load complete
Merging a Snippet
To merge a snippet, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following snippet to a file and name the file ex-script-snippet.conf. Copy the
ex-script-snippet.conf file to the /var/tmp directory on your routing platform.
commit {
file ex-script-snippet.xsl; }
2. Move to the hierarchy level that is relevant for this snippet by issuingthe following configuration mode
command:
[edit]
user@host# edit system scripts
[edit system scripts]
xii
3. Merge the contents of the file into your routing platform configuration by issuing the load merge
relative configuration mode command:
[edit system scripts]
user@host# load merge relative /var/tmp/ex-script-snippet.conf
load complete
For more information about the load command, see CLI Explorer.

not available in AFI airflow.
System Software
The Junos OS Evolved software on the QFX5220 provides Layer 2 and Layer 3 switching, routing, and
security services. Junos OS Evolved is installed on the switch solid-state drive (SSD).
For more information about which features are supported on QFX Series devices, see Feature Explorer.
You managethe switch using the JunosOS CLI, accessiblethrough the console and out-of-bandmanagement
ports on the device.
The QFX5220-32CD is supported on Junos OS Evolved Release 19.1R1 and later. The QFX5200-128C
is supported on Junos OS Evolved Release 19.2R1 and later.
The DC version, QFX5220-32CD-D, is supported on Junos OS Evolved Release 19.3R1 and later.
QFX5220 Component Redundancy
The following hardware components provide redundancy on a QFX5220 switch:
QFX5220-32CD power supplies—The QFX5220-32CD switches have one or two power supplies. Each
•
power supply provides power to all components in the switch. If two power supplies are installed, the
two power supplies provide full power redundancy to the device. If one power supply fails or is removed,
the second power supply balances the electrical load without interruption.
To provide power redundancy to the system, both power supplies must be installed. Connect power
source feed A to one power supply and power source feed B to the second power supply.
CAUTION: Do not connect feed A and feed B to the same power supply input
terminal.
QFX5220-128C powersupply modules—The QFX5220-128Cswitches have two to fourpower supplies.
•
The power supply modules are used in 2 + 2 redundancy mode. The system can run on two power
supplies without redundancy. If one power supply failsor isremoved, the other power supplies balances
the electrical load without interruption.
QFX5220-32CD cooling system—The QFX5220-32CD switch models have six fan modules and can
•
operate with one fan not in operation (5+1 redundancy). If more than one fan module fails and is unable
to keep the QFX5220-32CD within the desired temperature thresholds, chassis alarms occur and the
QFX5220-32CD switch can shut down.
23
QFX5220-128C cooling system—This switch model has 12 fans in 6 fan modules. There is one fan out
•
of the 12 fans forredundancy. This isknown as (5x2+1)+1redundancy). Any additionalfan failures cause
the switch to overheat, chassis alarms to occur and shutdown the switch.
QFX5220 Field-Replaceable Units
Field-replaceable units (FRUs) are components that you can replace at your site. The QFX5220 device
FRUs are hot-insertable and hot-removable: you can remove and replace one of them without powering
off the switch or disrupting the switching function.
CAUTION: Replace a failed power supply with a new power supply within 3 minutes
of removal to prevent chassis overheating. The QFX5220-32CD switch continues to
operate with only one power supply running. The QFX5220-128C can operate with
only two power supplies running. For best performance, we advise replacing failed
power supplies and fan modules as quickly as possible to protect against another
failure.
Table 4 on page 24 lists the FRUs for the QFX5220 device and actions to take before removing them.

NOTE: If you have a Juniper Care service contract, register any addition, change, or upgrade of
hardware componentsat https://www.juniper.net/customers/support/tools/updateinstallbase/.
Failure to do so can result in significant delays if you need replacement parts. This note does
not apply if you replace existing components with the same type of component.

The 10-Gbps network ports 32 and 33 support small form-factor plus (SFP+) transceivers.
Setting Port Speed and Channelization
The default port speed for ports 0 through 31 is 400 Gbps. Only QSFP-DD optics inserted in these ports
will link without configuration. See Table 5 on page 26.

NOTE: The QFX5220-32CD does not support autonegotiation between devices.
If a port already has a speed configured, you can manually configure the ports. To set the speed, use the
set chassis fpc FPC number pic pic number port port number speed 25|40|100|200|400 configuration mode
CLI command. For example, to set port 2 to 100 Gbps:
26
[edit chassis]
user@host#set chassis fpc 0 pic 0 port 2 speed 100g
NOTE: On QFX5220-32CD devices, there is a single FPC and PIC, which is always 0.
After you set a port speed, you can channelize the port into 4 independent 25-Gigabit Ethernet interfaces
by configuring the number of subports and speed. You should use the set chassis fpc FPC number pic pic
number port port number number-of-sub-ports 1|2|3|4 command. For example, to configure 100-Gbps
port 4 to four independent 25-Gbps interfaces:
[edit chassis]
user@host#set chassis fpc 0 pic 0 port 4 speed 25g number-of-sub-ports 4

QFX5220-32CD Network LEDs
The high-speed QSFP-DD network ports use a single bi-colored LED to indicate link status, activity on the
link, or a fault condition. The 10-Gbps SFP+ ports have separate bi-colored LEDs; the left LED indicates
link and activity and the right LED indicates fault conditions. See Figure 5 on page 27.
